Validity and Reliability of Video-Based Functional Physiotherapy Assessment of Subacute Knee Injuries

Summary

This study aims to validate a function-based physiotherapy assessment for subacute knee pain without using specific knee tests. Assessments are conducted either in-person or via video consultations in primary care. The study also compares the reliability of digital versus physical assessments to determine if video-based evaluations can provide sufficient diagnostic support and guide treatment decisions. The main questions this study aims to answer are: 1. Is a function-based knee assessment without specific knee tests valid compared to traditional in-person diagnostics using specific tests? 2. Is a video-based assessment based on history and function-based knee assessment without specific knee tests as valid and reliable as an in-person function-based knee assessment? 3. What is the interrater agreement of function-based knee assessments conducted via video compared to those conducted in person?
